今天，在回家的路上，看见一个卖豆腐的，妈妈要我帮她买豆腐。我帮妈妈买了一元钱豆腐，当我把豆腐递给妈妈的时候，发现我手上还有一元钱，原来我刚才忘了数钱了，我对妈妈说：“妈妈，我们拿来买吃的吧！”妈妈说：“不行！我们不能占别人的小便宜。”后来，我就把钱还给了卖豆腐的阿姨，阿姨说：“你真是个懂事的好孩子。”
Today, on the way home, I saw a tofu seller. My mother asked me to buy tofu for her. I bought one yuan tofu for my mother. When I handed the tofu to my mother, I found that I still had one yuan in my hand. I forgot to count the money just now. I said to my mother, "Mom, let's buy something to eat!" Mom said, "no! We can't take advantage of others Later, I gave the money back to the aunt who sold tofu. She said, "you are such a good and sensible child."
今天，我真高兴啊！
Today, I am so happy!
